GYNECOLOGICAL. AND SURGEONS GPERATENG=TABLE.

SPECIFICATION forming part of Letters Patent No. 300,337, ciatecldune 1'7, 188%.

Application filed August 31, 1883.

To all whom, it 'limig concerm;

Be it known that l', J. DALZELLE ALEX- ANDRE, a citizen of the United States, resid ing at Wooster, in the county of \Vayne and State of Ohio, have invented a new and useful fiynecological and Surgeon s Operating-Table, of which the following is a specification.

My invention relates to adjustable gyneeological and surgeons operating tables. Its object is to provide, by a simpler method than heretofore, an adjustable table having a flexible cushioned bed situated within a tableframe, and of such construction that the cushioned bed may be elevated, tilted, flexed, or rotated at the desire of the operator, so that the surface of the bed will place the patient in any desired elevation or posture for gyneframe, also joints of the stirrup-shafts with cologieal or surgical operation, and at the same time, by means of adjustable double-jointed stirrupshafts, to secure the legs and feet of the a patient in any desired position while the body lies upon the table for examination or opera tion.

My invention consists, first, of a flexible cushioned bed adapted to and situated within atable-franie made concave at one end, for reasons hereinafter specified, in connection with a device for tilting or flexing the cushioned bed in any desired angle or position by 1 means of two sets of tilting-bars, in combination with a perpendicularly-operating screwshait adapted to elevate the rise-post, and serve as a spindle upon which to rotate the bed, and vertically-adjustable pulley-tracks to support and curry each end of the bed, respectively, by means of tilting-bars provided with pulleys to run upon the tracks.

It consists, secondly, in adjustable doublehinged stirrupsha'fts,which are adjusted upon the concave end of the table-bed, and are adapted to be drawn out therefrom. The shafts of the stirrups are constructed with two joints each, the joints operating at right air gles to each other, and either or both joints adapted to be made rigid by means of a sliding sheath, which may be moved over the joints or hinges at the will of the operator. Heretofore but one joint has been employed, and that without any means of making the shaft rigid, or of allowing the stirrup to be elevated or lowered. This method is objeccushioued bed.

{No model.)

tionable because it does not admit of the control of the legs, as required in many cases. By

means of my double joints I am able to ad just the feet of a patient perpendicularly as well as laterally, or to make the stirrup-shaft rigid, when required, by means of the movable sheath; and, lastly, it consists in the combination of the parts above described.

Referring, to the drawings, in which similar letters of reference indicate like parts, Figure l is an isometric view of a gynecological and surgeons operating-table embodying my invention, and showing drawers and side curtains, which may be attached, and whereby the interior mechanism for operating the table is concealed. Fig. 2 is an isometric View showing the hed-frame raised above the tablesheath, upon and off the same.

The mechanism for operating the bed-frame which I claim, is hereinafter fully described and set forth.

J is the rim or tableframe, made concave at B, the foot end thereof, for the purpose of getting close to the lower parts of the body, as is necessary in gynecological operations. This rim or table-frame may be supported by legs, with drawers or panels, or hung with adjustable curtains, as shown, Fig. l, to hide the interior mechanism; but as to these or other mere variety of manuiactu re no claim is made. Within the table-frame J is the frame for the This frame is constructed with two leaves, L L, hinged. together at o". The leaf L has an extension-leaf, L, which may be readily attached to it by means of supportingbars adapted to enter the corresponding slots, V V, in the leaf L, as shown, when required for surgical purposes. Theseleaves constitute a flexible frame for the cushioned bed, and are supported upon a central rise-post, D, by means or a lateral tiltingbar, (J, and a longitudinal cross-bar, y, having adjustable arms o o, projecting upwardly to come into contact with the leaves, respectively. The lateral tiltingbar C is controlled and operated by means of a thread-gear, T, and crank It, whereby the bed-frame may be tilted laterally at the will of the operator. ihe tilting-bars E E are each hinged under the outer ends of the leaves, respectively, the

lower end of each bar having a sheathed pulley, p, which operates upon a corresponding vertically-adjustable track, 8, adapted to be elevated or lowered by means of the racks c c, pinions a a, and crank h. The tracks may be limited in downward movement by means of the ratchet and pawl c 25. By means of these vertically-adjustable tracks 8 s the outer end of the leaves, respectively, may be elevated or lowered independently of each other, or the bed may be rotated thereupon horizontally. The longitudinal cross-bar 3 is attached to the lower end of the risc-post D. The upwardly adjustable arms o e come into contact with the under surface of the bed-frame i 13, so that either or both leaves may be elevated or lowered with the corresponding movement of the These arms '1) e are also, adapted to be moved out of position, as shown at '11, so as to permit the ends of the leaves to be lowered independently of each other. The longitudinal tilting-bars E E extend below and underneath the corresponding track, s, so as to elevate or lower the tracks by elevating or lowering the ends of the leaves, respectively.

In the lower end of the pedestal D is a socket, A, to receive the upper end of a perpendicular thread screw, B, which enters the socket as a spindle, so as to admit of the pedestal being rotated upon the spindle when the bed is elevated above the frame J. thread screw B extends perpendicularly through astandard, F, attached to a bed-plate,

I, the spindle at the lower end of the screwshaft extending through the bed-plate, which forms a bearing for the same at A and holds it in upright position. This thread-screw is operated by means of a bevel-gear, G, and crank'H, in connection with the standard F; but I do not claim this device for operating the thread-screw. The-bed-plate I is firmly secured to the base of the table, so as of the bed-frame I extend the shafts on m to supportthe s tirrups P I through slots or clamps in the sides of the bed-frame L. These shafts are double jointed or hinged at O O,

The Y thej ointsorhinges acting at right angles to each other. The joint is adapted to lateral flcX- ion and the joint 0 to perpendicular flGXlOlI. These joints may either or both be made rigid at will by sliding over them the movable sheath K, as shown at K, thereby'enabling the operator to support the legs of the patient in any desired position while the body lies upon the operating-bed, or to secure the same against any movement whatever, as is sometimes necessary,

I am aware that flexible mattress-frames similar to those I use are not new, and that the vertically-moving racks 0, in connection with pinions a, operated upon a common shaft, have been heretofore used for similar purposes. I do not therefore claim such, broadly,

nor do I claim the stirrups I, except in combination wit-h shafts m, constructed as shown.

Having thus fully described my invention in'eonnection with certain features not claimed, what I claim as new, and desire to secure by Letters Patent, is the following, to wit: 1. In combination with table-frame J and supporting-structure with concave end B and in attress-frame L L, the rise-post D, adj ustingscrew B, standard F, gear G, and bed-plate I, the' latcral tilting-bar O with adjusting-screw T, and the longitudinal bar Y, provided with adjustable arms 7:, substantially as and for the purpose specified;

2. In combination with table-frame J, supporting structure, and mattressframe L L, the tilting-bars E, attached to each of said mattress-frames, provided with track-pulleys p, the verticallyadjustable pulley-tracks 8, together with racks c, pinions a, and the operatingshaft, provided with ratchet c and pawl t, and devices for giving an inclined position to the mattress-frame, substantially as and for the purpose specified.

3. In combination with the table proper, consisting of table-frame J supporting-structure, and mattress-frame L L, as shown and described, the stirrups P and stirrup-shafts m, the said shafts being provided with double joints 0 O, and movable sheath K, substantially as and for the purpose specified.

In testimony whereof I hereunto set my hand this 13th day of June, 1883.
